Hi all,
while testing the 'complex toolbar control' implementation I'm working
on, I ran into a problem with the image size.
Toolbar images should be 16x16 or 26x26 pixel.
I have prepared the two set of images but I can't figure out when I have
to change them.
I mean, the user has three selections available: Automatic, Small, Large.
What can I monitor to detect when such changes are applied to my toolbar
in order to set the correct image size?
For the Small and Large selections I can use an 'XChangesListener' to
the right
configuration parameter (e.g. create read-only view that listens for
changes), but I have no idea about how the Automatic one.
Any suggestion will be appreciated.
Hi Giuseppe,
I think your idea with the XChangesListener is the best way to get
notifications about a selection for small and large icons. The automatic
selection is a problem as you already found out. Currently there is only
a C++ class which notifies about icon changes, therefore this
notification is not available for extensions. For what complex toolbar
control do you need this notification? I can think of using the
the 'ControlType' value is ImageButton, where the custom image is
dynamically changed to reflect the state of an internal extension status
variable
XControlNotificationListener interface to provide this kind of
information to a complex toolbar controller. As the interface can
transfer any kind of information without being changed.
That would be a great idea, I suppose that the toolbar already receives
the size change notification and routing it through the
XControlNotificationListener interface seems to be the most sensible
thing to do.
